To all whom it may concern Be it known that 1, Max JACOB, a sub ect of the Emperor of Germany, residing at Berlin, Germany. inv the kingdom of Prussia lator are at all times locked except when under the control. of the actuators therefor and the transfer devices cotiperating with said elements. I

' Another object ofthis invention is to pro vide an improved recording mechanism whereby an impression is made upon a slip from a set of type carriers and the slip then fed so that a duplicate impression may be made upon a second slip.

A further object of this invention is to provide an improved form of type carriers which in addition to printing the digit, print the word designating thedigit recorded and -also a character indicating the denominational value of the recorded digit. By printing these characters in juxtaposition to the digit it reduces to a minimum the danger of altering the recorded digit without detection.

lVith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment-of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

Fig. 11 is adetail. view of one of the sales slips showing an impression taken from the improved type carriers.

These improvements have been shown as applied to a machine of the type well known on the. market and which isexe'mplified in the following patents: Cleal and Reinhard No. 580,378 granted April 13, 1897 and Thomas Carroll No. 754,049 granted March 8, 190% but it is to be understood that these improvements may be with equal facility applied to other well known types of machines' The machine to which these improvements have been applied, as is fully shown and described in the aforementioned patents, comprises a plurality of banks of keys 1, each bank of which controls the differential movement of a segment 2, these segments being mounted upon a shaft 3, which is rocked by suitable connections 4 from a shaft 5, which is given a complete rotation upon each operation of the machine. Each of the segments 2 meshes with an enlarged gear 6, which in turn meshes with smaller gears 7 and 8 of the accumulating and indicating mechanisms respectively.

As hereinafter more particularly pointed out the improved machine is provided with two accumulators,.upoh one of which is accumulated the total sales of any desired period, such as a day,week or month, while the other accumulator is used for the purpose of accumulatingthe total of different items purchased by a customer, after which the last mentioned accumulator is cleared or reset to here ready for the accumulation of another series of items. 1

The indicating mechanism comprises a plurality of disks 9 3) each having suitable indicia thereon, each disk also carrying a large gear 10. These gears 10 of the indicating disk mesh with pinions 11 loosely mounted upon a transverse shaft 12, these pinions in turn meshing with gears 13 loosely mounted upon a shaft 14: which is supported by side frames 15, which also support the previously mentioned shaft 12. Adjacent to each of the gears 13 is a similar gear 16 to which is fastened a pinion 17, these pinions 17 in turn meshing with gears 18 forminga part of the elements of the improved accumulator. In addition to the gear 18 each accumulating element comprises a disk 19, carrying a plurality of digits and having formed on the surface thereof a groove 20 having a cam portion 21 (Figs. 3, 1, and 5).

The gears 13 and 16 which are arrangedin pairs are normally disconnected and each pair is arranged to be connected by a pinion l as 22 (Figs. 3 and .7 these pinions being carried by arms 23 extending downwardly from a rock shaft 2-1. This shaft 2 1, near the center thereof, has extending upwardly therefrom an arm 25, the upper end of which is provided with a roller 26, that plays in a cam groove 27 formed in a disk 28 secured to a shaft 29, which shaft is given a complete rotation upon each operation of the machine. The shape of the cam groove 27 issuch that just previous to the actuating movement of the segments 2 controlled by the keys 1, said cam groove will rock the shaft 21 in such a manner as to carry the pinions 22 into engagement with the gears 13 and 16 so that the movement imparted to the actuating segments 2 will be transmitted through the indicating mechanism to the elements of the improved accumulator. This manner of connecting elements of the.

1 improved accumulator with the actuators is substantially identical tothe manner employed in actuating the first mentioned accumulator which comprises the gears 7, which method is described in detail in the aforementioned Cleal and Reinhard patent.

Transfer disks 30, each having a single tooth 31, are splined to the rotary shaft 25) so that said disks may rotate with the shaft and yet have a lateral movement independent thereof. Certain of the teeth of the gears 18, which are part of the accumulating elements, are partially cut away, as shown in Figs. 2 and 6, so as to permit the rota tion of the transfer disks 30 and at the same time lock the accumulating elements comprising the gears 18 from m vement on account of the teeth adjacent to the cut awn teeth contacting'with the peripheries of the greases disks 30. These disks 30 are provided with cut away portions 32, which portions, when they a present themselves to the gears 18, permit the operation of the accumulating elements of which said gears are a part. Just previous to the locking surfaces of the disks 30 passing out of engagement with the gears 18 the coupling piniens 22 are moved.

into engagement with the gears 13 and 16 and remain in engagement therewith while comprising the gears 18 and wheels 19 have been actuated by the movement of the seg ments if, the locking surfaces of the disks 30 engage with the gears 18 and prevent further movement of said accumulating elements. I

If any of the accumulating elements, dur-, ing the actuation thereof, is moved a sufficient extent to bring the zero to reading positiou the cam portion 21 of said element will engage with a pin 33 projecting d0wn-' wardlv from an arm 34 and shift said arm laterally upon a shaft .Each of these arms, of which there is one for each accumulating elcmcnt.-is splincd to the shaft 35 by a rib 36 which extends through flanges 87 struck up from said arm. The flanges of each arm extend rcurwardly to each side of one of the transfer disks 30. From this it will be seen that as one of the accumulat ing elements passes from nine to zero it will cam the arm 3% laterally upon the shaft 35 and, through the flanges 3?, shift its transfer disk. This shifting of the transfer disk brings its single tooth b1 into the same plane as the teeth of the gear 18 of the next higher accumulating element so that when said transfer disk is rotated its tooth will engage with the teeth of the gear 18 and rotate the accumulating element to bring the next higher digit on said element into leading position. Previous to the engagement of the tooth 31 of the transfer disk 30 with the gear 18 the coupling pinions 2? so that immediately before the transfer and inmiediatcly thereafter the accumulating elements are locked from operation.

Lin

Upon the beginning of the succeeding operation of the. machine the displaced arm 39: and its companion transfer disk 30 will be returned to their normal positions by the shifting of. the shatt id supporting the arms Y which projectsa roller l extending from an. arm {l1 secured to the shaft Immediately upon the beginning of rotation of the disk 38 the shaft will he rocked car-- lying all of the pins above the surface of the disks l9. l'lhile the arms 3% are in this position the cam portion of .a groove 4:2, Figs. l and formed in a disk it will. act upon a roller liprojecting from disk 45 secured to a. shaft 35 and shift said shaft laterally. Projecting from. the shaft 35 between the flanges b? of each are which engages with one of the flanges of the displaced arm 8-1 as the shaft is shifted and thereby return said arm to normal position with its pin in position to cooperatewith the groove of its companion accumulating element. This shifting of the displaced arm will also return the dis placed transfer disk by the flanges 37.

Innnediately after being shifted the shaft is rocked into its normal position by the cum disk carrying the pins of the arms 34: into their respective grooves 20.

ll'hile in normal position and until the pinions couple the gears 13 and 16 forming a part of the actuating mechanism for the accumulating elements the latter are held in proper alinement by a bar 120, Fig. 6,

whicii is supported by arms 1.21 pivoted to the side frames as at 122. One of these arms 12]. extends rearwardly beyond its pivotal point and has extending from its extreme rearward end a roller which plays in a cam groove 12lformed in a disk 1255 secured to the rotary shaft :29. The timing; of the cam dis: is such that immediately after the coupling of the accumulator elements to the actuating: mechanism by the pinions the ulining bar'iQO is Withdrawn from the gears 18 and held in its witlnlrawn position until near the end of the rotation .i'nechanism located The accumulating .above the incicators is arranged to he used none 3% is a. pin

'which surround a transverse shaft 51.

to be cleared or reset to Zero, after the items comprising a purchase have been accumulated thereon, by mechanism Well known in the art and which is fully disclosed in the aforesaid Clea]. and Reinhard patent.

The next feature of the invention to be dcascribed relates to the recording mechanism whereby an impression is taken upon a plurality of slips from a single set of type carriers one of said slips being fed out of cooperative relation. with the type carriers after an impression has been taken thereon so that an impression, may be taken upon the second one of said slips.

In newspaper oifices it is desirable Where a person inserts an advertisement in the newspaper, that he be furnished with a. copy of said advertisement with the cost thereof, the date of the ad ertisement'and some suitable identifying character, such as a consecutive number. printed thereon while a duplicate of said copy is sent to the composing room to be set up. These duplicate copies are returned to the office from the composing room and kept on file so that in case a complaint is made of an error in any of the advertisements, it may be quickly checked up by comparing the copy held by the person making the complaint with the copy retained in the oflice The differential movements of the segments '2 are transmitted to a set of type carriers (Fig. 9) by rollers 46 projecting from said segments, which play in elongated slots 4:? formed in arms 48 fast to the inner ends of series of nested sleeves l9. At their outer ends these sleeves d9 are pro vided with segments 52 'which mesh with pinions suitably secured "to the type carriers 50, all of which is fully shown and de scribed in the aforementioned Carroll 1 atent. These amount type carriers 50 are loosely mounted upon a. transverse shaft 5i shown as their construction "and manner of operation is well known in the art.

Previous to'the operation of the niacliine,

slips 55 and :36 are placed upon platforms 5? and 58. respectively, the former slip being placed upon its platform from the front of the machine with its upper end directly beneath the type carriers. while the latter strip is placedupon the platform 58 from the side of the machine with its lower end beneath the type carriers and the slip 55. The platform 58 "for the slip 5G is provided with forwardly extending fingers =39 which guide the upper end of the slip as the latter is inserted in the machine. in ink ribbon 30 passes around the type carriers 50,

j (it and an absorbent ink roller Thisj lion is fed intermittently upon operation of the machine by a'raised portion i i of a' drum G3 which raised por- 5' tier; impinges the ribbon (30 between it and a roll r as; during each rotation of the drum 63; ';tl1e y lOllEl 64 being suitably mounted upon, the printer frame. The drum 03 is secured to the shaft 65 which is given a com- 14) plete"rotation upon each operation of the machine.

While the machine is shown as being operatcdby a crank handle '66, it is to be understood that any of the well known power devices may be employed. The handle is providcd with .a suitable pinion, not shown, which drives a largeintermediate gear 67, and whichintermediate gear through gears 38 and 69 rotates the shaft 05 as fully shown in the aforementioned patents, the gear 69 being secured to the shaft 65'. ,i3ecured to the shaft is a collar 71 (Fig. 10%, provided with shoulders 72 and 7 3, whgio l co'operate with shoulders Hand 75, 2.5 respectively, ,of a hub 76 of a cam disk 77, wlrielris loosely mounted upon the shaft 65, Upongthe rotation of the shaft the shoulder 72 0f collar 71 secured to said'shaft will conc tact with the shoulder 74: of the hub '76 of the cam disk 77 and rotate the latter with theshaft. 65. As this cam disk 77 is rotated, it willflower a pitinan '78 by means of a roller-J79, projecting from said pitman riding -uponzthesurface of the cam 77. The lower endief this pitman 78 isconnected to a lever 80,: which is pivoted. upon a rod 81 at its rear end and at its forward end carries a platen 88%; A. spring 89, the ends of which "are; connected to the platen lever 80 and a part of the frame work of the machine, keeps the roller ,79 of the pitman 78 in constant contact with the surface of the cam disk 7-7. VJhile the type-carriers are being adjusted, the roller '79 of the pitman 78 rides upon the surface of the disk 7'? and after said type carriers have been adjusted, the roller 79 will pass into a reduced portion 90 of the dish 7'? under stress of the spring 89, thereby permitting .the platen S8 to take an impression from. the type carriers upon the slip 55,

which vis the uppermost one of the two slips inscrted Immediately after the taking of this impression, the slip is fed forward,

as hereinafter described, and the roller 79 is engaged by a projection 91 of the cam disk 7'7, by which the pitman 78 will be lowered and the ol ten lever 80 rocked about the'rod 81. r l the cam. projection 91 passes away from th roller 79, the spring =e the pl the type carriers to ta he an impression upon the-second slip 50, it being understood that the sl"p 55 has been fed forward. twill-be n: there is a slight 95 lost motion between the saoulders 73- and 5 gcated so as to straddle the shaft 65.

into contact withshaft could beso rotated that the roller 79 would slowly pass into the reduced portions of the cam and thereby prevent the taking of a legible impression from the type carrlers.

The ratio of the gearing between the operating handle 66 and the shaft 65 is such. that for each two rotations of the handle 66, the shaft 65 will be given a complete rotation, while the large intermediate gear will be given only a half of .a rotation. Formed in the side of this intermediategear 67 is a double cam groove 92 in which plays a roller 93 projecting approximately from the center of a plate 94. The upper end of this plate is provided with an elongated slot 95 through which extends the stub shaft 96 upon which the gear 67 is mounted. The lower end of this plate 94; is provided with a rack portion 97, which meshes with a pinion 98 secured to an arm 99 loosely mounted upon a stud 100 projecting from the side frame 15 of the machine, At its lower end this arm 99 is provided with a lateral extension 101 to which is secured a piece of rubber 1022 or some other suitable resilient material. The shape of the cam groove 92 is such that upon each half rotation of the gear 67, which is equivalent to a complete operation of the machine, the arm 99 will be oscillated by the rack. plate 94. This plate 94 is guided at its lower end by a roller 103 projecting fromthe side frame of the machine.

A feed roller 104: is mounted upon the outer end of arm 105 which is secured to a rock shaft 100, this roller being arranged to coiiperate with the rubber plate 102 secured to he i eral extension 101 of the arm 99, as hereinafter described. Secured to and eX- tending upwardly from the rock shaft 106 is an arm 10'? to the upper end of which is connected the forward end of a pitman 108, the rearward end of the latter being bigun r0- jecting from the pitman 108 near its bifurcated end is a roller 109 which extends into the cam groove 110 formed in the disk secured to the drum 63. The shape of the groove 110 is such that the shaft 106 is rocked through the pitman 1.08 so asto bring theroller 104; into the path of the movement of the rubber plate 102 carried by the oscillatory arm 99, so that the slip 55 will. be impinged between the plate 102 of the roller 104: and. by the continued movement of the arm carrying, the platen 102 will advance the slip 55 after an impression has been taken thereon. Immediately after the sllp I 55 has been fed forward, the roller-1% is lowered so that the rearward movement of "the arm 99 carrying the rubber plate 102 will not return theslip 55 to interfere with the. taking of an impression upon the second slip 56.

In pay-cashier systems, that 1s, where the customer receives a check or sales slip from the clerk waiting upon her, which check or slip is to be tendered for payment at the cashiers desk located in another part of the store, proprietors have discovered that amounts printed upon the check or slip have frequently been altered and in order to reduce to a minimum this danger of alteration, the amount type carries are constructed follows: Engraved in juxtaposition to each of the digits of the amount type car riers, as plainly shown in Fig. l and by the impression taken upon the sales slip 55 in Fig. 11, is a word designating the numericaLvalue as well as a word designating the denomination to which the digit belongs. From this it will be seen that it is necessary to aiter the word or character designating the digit,'as well as the digit itself to avoid detection which reducesthe chances of sucmen't herein shown and described but that it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.-
